help me in defending Quran

[ابو علي الفلسطيني]

بسم الله الرحمن الرحيم
First,I would like to ask you sister not to be affected by his words because his porpose is to confuse you, and i would like to advise you to read books about Isalm and christianity written by muslim people and order to know how to discuss him and they are availbe in this site in the libraryمنتدى الكتب
I would like to give you these facts about the bible to discuss him with. First, Mark,Luke who wrote the bible they aren't Jesus disciple and they never saw or heared him. Secondly, the original versions of the bible have disappeared. so what can prove to me that the current bible is God's words? how did jesus's disciples wrote the bible?? did god talk to them directly or what? they said thay wrote the bible with inspiration how come!!!
The Old testament says that god is one but the new testemant says that god has a son. what is his explanation for this contradiction?
Jesus' language was Aramic but no bible is availabe in Aramic language?
christianity says that jesus' disciples recieved revelations from god but jesus himself received no revelations? who is the prophet jesus or his disciples??
the bible has no revealed verse that mark its begining or its end.
the bible includes thousands of mistakes by the admission of christian scholars from 30,000 to 50,000 is this book which contains all these mistakes arevelation from god???
christianity says that god is three gods in one! is this the logic and the wisdome believe? it doesn't make any sense to say that gos is one in three or three in one but Islam says god is one which a very simple logical understanding.
The church gave jesus a strange series of promotions from a son of man to a son og god, which is more logic?
they claim jesus was crucified, how could crucifying someone may save the whole world? is this logic?
they say when jesus was crucifie he was arrested by the soldiers,beaten,spat on, whipped, kicked, mocked of, laughed at, and finally hanged on a cross. But Islam says that jesus was honored and saved by god. who is more logic?
I would like you my sister to read this verse from the holy Quran to know what theway god shall talkwith people.
"it is not given to any human being that Allah should speak to him unless (it be) by revelation , or from behind a veil,or (that)He sends a massenger to reveal what He wills by His leave"الشورى 51
so god makes it clear how He would talk to people (by a massenger) and not by anything else.
we must be sure also that christianity tells many myths and many mysterious things that is hard to believe.
they said that the devil stands in the way of jesus and talk to him. did he belive in this?? if he belived then he must belived in the (Jinn)because devil is a part of the Jinn. if he doesn't believe then christianit is wrong and he must refuse it
i hope what i have said may help you and again never doubt your faith in god and islam and the holy Quran and read English books for this purpose as much as you can and write points for things he asks you about
thank you
